ABSTRACT:
The high-voltage switch filled with an insulating medium has at least one interrupter chamber (3, 3a) fixed on a central housing (2) supported by an insulator column (1). Fitted in the region of the at least one interrupter chamber (3, 3a) is at least one measuring head (6), in which a sensor (9) picks up current-proportional measuring signals. These measuring signals are transmitted via an optical waveguide (16) at ground potential for further processing.
A high-voltage switch is to be created in which sensors (9, 39) can be fitted by simple means in easily accessible manner outside in the region of the interrupter chamber (3, 3a). This is achieved by the at least one measuring head (6) being accommodated in a housing suitable for fitting outside on the high-voltage switch. In this arrangement, the optical waveguide (16) is led pressure-tight through a closure cover (38) of a fitting opening into the central housing (2).
